Superhuman.

Superhuman is the company that operated as Grammarly for its first sixteen years. Founded in 2009 by Max Lytvyn, Alex Shevchenko and Dmytro Lider, it began as a grammar and plagiarism checker sold to students, was bootstrapped to profitability, and did not take institutional capital until a $110 million round in May 2017. On 29 October 2025 the parent company took the name of a business it had bought four months earlier and became Superhuman, keeping Grammarly as a product name rather than a corporate one.

The company now sells a suite rather than a single tool. Grammarly remains the writing assistant that runs inside other people's applications; Superhuman Mail is the email client acquired in July 2025; Superhuman Docs is the collaborative workspace formerly called Coda, renamed on 8 July 2026; and Superhuman Go, introduced alongside the rebrand, is a proactive assistant that coordinates agents across the applications a user already has open. The company says Go works across more than a million apps and websites.

Distribution, not model development, is the asset. Superhuman does not train frontier models; it embeds a thin, permission-aware layer into the browser and desktop surfaces where knowledge work already happens, and routes work to third-party models and to partner agents from firms such as Box, Gamma and Wayground. As of February 2026 the company reported more than 40 million daily users and 50,000 organisations on the platform.

The financing history is unusual for a company of this scale. Total equity raised is roughly $400 million across three rounds, the last of which set a $13 billion post-money valuation in November 2021. The $1 billion raised from General Catalyst in May 2025 was non-dilutive, drawn from the firm's Customer Value Fund and repaid out of revenue, which left the 2021 valuation and the cap table untouched while funding sales, marketing and acquisitions.

That capital has been spent on buying product surfaces: Coda in December 2024, which also brought Shishir Mehrotra in as chief executive; Superhuman in July 2025, last valued privately at $825 million; the Portuguese spreadsheet-automation startup Rows in February 2026; and the AI-detection company GPTZero in June 2026. Reported annual revenue was above $700 million as of May 2025.
